{ "type": "Collection", "stac_version": "1.0.0", "id": "bio-oracle", "title": "Bio-ORACLE v3.0 \u2014 Global Marine Environmental Layers", "description": "Global marine environmental layers from Bio-ORACLE version 3.0, aggregated to H3 hexagonal cells at resolution 6. This bucket holds the 2010-decade baseline, depth-mean realm: temperature, salinity, current velocity and direction, nitrate, phosphate, silicate, dissolved oxygen, dissolved iron, primary productivity and pH, together with the static benthic terrain layers bathymetry, slope, aspect, topographic position index and terrain ruggedness index.\n\nThese are the standard covariates for marine species distribution modelling. Joined on h6, they give a per-cell environmental profile that can be combined with occurrence records elsewhere in this catalog.\n\nCurrent direction and aspect are compass bearings and are each published as a separate sine and cosine collection, because a bearing cannot be averaged arithmetically across the 0/360 wrap. Recombine with (degrees(atan2(sin, cos)) + 360) % 360.\n\nThis dataset has no h8 column, and that is deliberate rather than a defect. The Bio-ORACLE source grid is 0.05 degrees, about 5.5 km, so one source pixel covers roughly 31 square kilometres. An h6 cell is 36.1 square kilometres, which matches the pixel; an h8 cell is 0.74 square kilometres, which would replicate each measured value across about 42 identical cells and publish apparent detail the source does not have. To combine this with an h8-native dataset such as GBIF or OBIS occurrences, roll that dataset up to h6 or h5 with h3_cell_to_parent, rather than expecting an h8 column here.\n\nCite both: Assis, J., Fernandez Bejarano, S.J., Salazar, V.W., Schepers, L., Gouvea, L., Fragkopoulou, E., Leclercq, F., Vanhoorne, B., Tyberghein, L., Serrao, E.A., Verbruggen, H., De Clerck, O.
